Yintoni i-UV-144 CAS 63843-89-0?

UV-144 umgubo omhlophe ukuya kotyheli kancinci, uhlobo lwe-NOR olusebenza kakuhle luthintele isizinzisi sokukhanya se-amine, esifanelekileyo kushishino lokugquma umgubo. Izizinzisi ze-amine ezithintelweyo ezine-phenolic antioxidant ezithintelweyo kancinci zinokunciphisa ukuqhekeka kunye nokulahleka kokukhanya, nto leyo eyandisa kakhulu ubomi benkonzo yeefilimu zepeyinti.

Isicelo

Uhlobo lwe-UV-144 olusebenza kakuhle lwe-NOR luthintele isizinzisi sokukhanya se-amine, esifanelekileyo kwishishini lokugquma ipowder. Izizinzisi ze-amine ezithintelweyo ezine-phenolic antioxidant ezithintelweyo kancinci zinokunciphisa ukuqhekeka kunye nokulahleka kwe-gloss, nto leyo eyandisa kakhulu ubomi benkonzo yeefilimu zepeyinti. Kwangaxeshanye, inepropati yokwenza i-powder coatings ibe nokungqubana kwaye itshajwe, nto leyo ephucula izinga lokugquma ipowder. Isetyenziswa kakhulu kwi-powder coatings, i-coil steel, i-automotive coatings, njl.
